Hi, I am having some issues regarding downloading the canvas snapshot on mobile.
Before I ramble on, my ideal goal is to click a button and it download the canvas as an image to my camera roll (iOS).
Unless I'm doing something wrong, invoking the download of the canvas snapshot does not work inside safari on mobile. What I can do is open the URL of the canvas snapshot and this works, and from there I can "hold down" on the image and "save image" as you would anywhere else on the internet. This I thought would work just fine, until I added my "web app" to the home screen for "full screen" viewing at which point when you hold down on the image, it simply doesn't ask to "save image"?
Does anyone know a work around to how I can do this?
